A 12-year-old Toronto girl was charged with nine firearms charges, possession of a prohibited device and possession of property obtained by crime.

A 16-year-old girl from Toronto has been charged with 19 weapons-related offences and two counts of possession of property obtained by crime.

A 17-year-old male from Toronto also faces nine weapons-related offences, possession of a prohibited device, possession of property obtained by crime and two counts of failure to comply with probation.

A second 17-year-old Toronto male, a 39-year-old Toronto woman and two 16-year-old Toronto boys also face nine firearms charges, in addition to one count each of possession of a prohibited device and possession of property obtained by crime.

Police also charged 18-year-old Abdullahi Hassan and 24-year-old Nicole Brand, both of Toronto, with the same 11 charges.

All of the suspects appeared in Toronto courts Wednesday morning and the names of those under 18 cannot be released under the provisions of the Youth Criminal Justice Act.

Const. Caroline de Kloet said the 39-year-old female suspect also cannot be identified as it may compromise the identify of the underage suspects.

She added that police had been at the house on a separate call before a search warrant was requested.

De Kloet would not specifically comment on the degree to which the youth were involved, but said all of the suspects were in the house where the weapons were found.

She added that all of the suspects were involved in the investigation and the subsequent charges were warranted.

The firearms-related charges ranged from careless storage of a firearm, to possession of a restricted firearm with ammunition, carrying a concealed weapon and tampering with the serial number of a firearm.
